An event generator for decays at NLO in SMEFT matched to a parton shower

Livia E. G. Maskos, Benjamin D. Pecjak, Shakeel Ur Rahaman +1

We present a Sherpa implementation of NLO corrections in dimension-six Standard Model Effective Field Theory (SMEFT) to the benchmark process . The calculation includ…

Feasibility of ultrarelativistic bubbles in SMEFT

Upalaparna Banerjee, Sabyasachi Chakraborty, Suraj Prakash +1

A first order electroweak phase transition probes physics beyond the Standard Model on multiple frontiers and therefore is of immense interest for theoretical exploration. We condu…

One-loop Effective Action up to Dimension Eight: Integrating out Heavy Fermion(s)

Joydeep Chakrabortty, Shakeel Ur Rahaman, Kaanapuli Ramkumar

We present the universal one-loop effective action up to dimension eight after integrating out heavy fermion(s) using the Heat-Kernel method. We have discussed how the Dirac operat…

EFT, decoupling, Higgs boson mixing, and higher dimensional operators

Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +3

The effective field theory (EFT) framework is a precise approximation procedure when the inherent assumptions of a large-scale separation between the Standard Model (SM) and new in…

Integrating out heavy scalars with modified EOMs: matching computation of dimension-eight SMEFT coefficients

Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +2

The shift in focus towards searches for physics beyond the Standard Model (SM) employing model-independent Effective Field Theory (EFT) methods necessitates a rigorous approach to…

Memories of quenches in operator mixing

Joydeep Chakrabortty, Diptarka Das, Bidyut Dey +2

We work perturbatively with an interacting quantum field theory comprised of two distinct scalar fields. In this theory, we introduce a sudden quench of the mass of one of the scal…

EFT Diagrammatica II: Tracing the UV origin of bosonic D6 CPV and D8 SMEFT operators

Wrishik Naskar, Suraj Prakash, Shakeel Ur Rahaman

In recent times, SMEFT, along with a superlative repertoire of theoretical and computational tools, has emerged as an efficacious platform to test the viability of proposed BSM sce…
